WILLIAM EDWARD DAVIS, OF-JERSEYCITY, NEW JERSEY,

Letters Patent No. 92,284, dated July 6, 1869 MROVEMENT IN TELEGRAPH-SOUNDBRS.

iho Schedule referred to in these Letters Patent and inaking part of the same.

To all whom'it may concern:

Be it known that I, \VILLfAliI EDWARD DAVIS, of Jersey City, in the county of Hudson. and State of New Jersey, have invented a new and improved Tele graph-Sounder; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and "use the same, reference being had to the accompanying drawings, forming partot' this specification, in which- Figure 1 represents a side elevation, partly in section, ofniy improved telegraph-soimder.

Figure 2 is a horizontal section of the same, taken' of the other parts that pertain to this apparatus, as

hereinafter more fully described.

The improvement consists Y chiefly in constructing the sounding-post, or column A, of hard rubber, made in cylindrical form, so as to be hollow, as shown.

This column is fitted upon a metal ring, B,'which rests on the base 0, and is covered by a metallic cup, D.

A bolt E, made of steel, is fitted through the base and cap, and is fastened, at the lower end, in a recess of the base by a nut, 'a,.'while its upper end is above the cap, clamped by a nut, b.

The base is perforated below the cylinder, as at c, to allow afree escape of the sounding-waves.

The upper end of the steel rod E will, when struck by a steel pin,d, that is fastened to the armature-lever F, cause a clear soundto be produced, which is loud enough to be readily understood by all telegraphers.

The armature-lever, pivoted to a standard, or stand= ards, G, is acted upon by the magnet H, and has its rear end weighted and drawn down by a spring, 0.

This-spring has its lower end fastened to a cord, f,

which is wound upon a-pin, g. I

The pin 9 has its hearings in a stud, or standard, n,

that has two slots cut at right angles into its upper end.

The, one slot, 2', is to admit the cord f, while the other, j, parallel to the pin g, serves. to impart the proper spring to the standard for holding and clamping said pin, to prevent it from working loose.

Having thus described'iny invention,

What I claim as new, and desire to secure ers Patent, is-

1. The hollow sounding-column A, when made oi I hard rubber, and covered by a metallic cap, substantially as herein shown and described.

2. The combination of the perforated base 0 and steel bolt E, with the hollow rubber column A, cap D, and armature-lever F, all arranged and operating substantially as herein shown and described.

3. The stud, or standard h, carrying the pin g, when provided with double slots, 6 and j, substantially'as and for the purpose herein shown and described. I i WILLIAM EDWARD DAVIS.
